The ceilings in roberto's house are 12 feet high. how many meters high are the ceilings?

The ceiling is 3.6576 meters high

Step-by-step explanation:

To solve this problem, we will follow the steps below;

We can easily use proportion to solve this.

Let x be the height of the ceilings in meters

1 meter = 3.28084 feet

    x   =       12 feet

cross-multiply

3.28084 x  = 12

Divide both-side of the equation by 3.28084

3.28084 x/ 3.28084   = 12/3.28084

(On the left-hand side of the equation 3.28084 at the numerator will cancel-out 3.28084 at the denominator, while on the right-hand side of the equation 12 will be divided by 3.28084)

x   ≈  3.6576 meters

Therefore the ceiling is 3.6576 meters high

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

answer: .75 km
